Shenzhen Anyi Technology Launches ONETEST-502XPS: Next-Generation Negative Oxygen Ion Sensor for Precision Air Quality Monitoring

Shenzhen, China — Shenzhen Anyi Technology Co., Ltd., a leading manufacturer specializing in atmospheric ion monitoring solutions, proudly announces the official release of the ONETEST-502XPS RS232 Air Ion Sensor. Engineered for high-precision outdoor environmental monitoring, this advanced negative oxygen ion sensor delivers professional-grade measurement capabilities ranging from 0 to 2 million ions per cubic centimeter, setting a new benchmark for air quality assessment worldwide.

Advanced Coaxial Binary Cylinder Technology

At the heart of the ONETEST-502XPS lies the proprietary “coaxial binary cylinder” measurement principle. This innovative design ensures exceptional measurement consistency, high precision, and remarkable stability across diverse operating environments. The sensor autonomously detects both positive and negative ions in ambient air, providing a comprehensive picture of atmospheric ion concentration — a critical indicator of air freshness and environmental health.

The device achieves an impressive resolution of 1 ion per cm³ with a measurement accuracy of ±10%, making it one of the most reliable instruments available for professional air ion monitoring applications. With an ion mobility rating of 0.4 cm²/V·second, the ONETEST-502XPS delivers rapid and accurate readings even under fluctuating environmental conditions.

Key Features at a Glance

• Dual-ion Detection: Automatically measures both positive and negative air ions with intelligent gear switching
• Wide Measurement Range: 0–2,000,000 ions per cm³, suitable for diverse monitoring scenarios
